Meet the Executive Committee of Araiso Private High School, a group of five students whose motto is “Ridiculing the weak and bullying the strong.” At the heart of this organization are Kubota Makoto and Tokito Minoru, two bad boys who take care of any trouble at the school in their own unique (and violent) way. If you are familiar with Minekura’s other works or if you paid attention to the Wild Adapter description, you’ll recognize the names of Kubota and Tokito as main characters of the WA manga. No reference is ever made to the Wild Adapter story line in Araiso, which is slightly more upbeat than the dark Wild Adapter. This manga is also known as Shiritsu Araiso Koutougakkou Seitokai Shikkoubu referred to as simply Executive Committee.
